Germ layers are produced during gastrulation and are the initial tissue layers of an embryo. Sometimes they are called embryonic tissue layers. They will develop into all the different tissues and structures present in an adult animal. 1  Ectoderm is the outermost layer of cells.  Mesoderm is the middle tissue layer.
The cavity inside the blastula is called blastocoel, and its outer single cell layer is called blastoderm. Gastrula. The continuous development of blastula finally results the gastrula. The conversion process of the blastula into gastrula is called âgastrulationâ.Gastrulation is followed by the organogenesis. Gastrula is composed of three primary germ layers, which eventually give rise to organs in the late embryo. The primary germ layers are ectoderm, mesoderm, and endoderm.he three germ layers of gastrula interact in various ways to form organs, hence called organogenesis. Since, blastula and gastrula occur separately as different structures in different phases, there are some differences can be observed between both structures. Blastula.
